IMPROVEMENT IN COOKlNG-STOVES.

Specification forming part of Letters Patent No. 141,508, dated August5, 1873; application filed May 10, 1873.

To all whom it may concern:

Be it known that I, WILLIAM W. KARSH- NER, of Aubrey, in the county ofJohnson and State of Kansas, have invented a new and useful Improvementin Cooking Stoves, of which the following is a specification:

Figure 1 is a top view of my improved stove, the boiler-hole coversbeing removed. Fig. 2 is a front view of the same. Fig. 3 is a verticallongitudinal section of the same taken through the line 00 m, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved cooking-stove,which shall be so constructed that all the heat may be thrown to the topof the stove and directed to one or more of the boiler-holes, asdesired, to enable cooking to be done without heating the lower part ofthe stove; or all the heat may be made to pass aroundthe oven, to enablethe baking to be done without heating the upper part of the stove; orthe heat may be made to circulate through both the upper and lower partsof the stove before escaping into the chimney; or may be made to passdirectly into the chimney without heating either the upper or lowerpart, thus enabling the fuel to be used with great economy, and the roomto be kept comparatively cool when desired, it being necessary to use nomore fuel than the special purpose may require. The invention consistsin the improvement of stoves, as hereinafter described and pointed outin the claim.

A represents the body of the stove, which is constructed in the ordinarymanner. B is the fire-chamber, whiclris provided with a fire-grate, (J,in the ordinary manner. The fire-chamber B is arched or lined upon thetop and sides with fire-brick, soap-stone, iron, or equivalentsubstance, D. The front, the door, and the lower part of the rear shouldalso be lined, an opening being left at the upper part of the rear endfor the heated products of combustion to pass through, which openingshould be provided with a damper, E. The top or arch of the lining D,which should be at a little distance below the top plate of the stove,should have holes formed in it corresponding with and directly beneaththe boiler-holes in the said top plate of the stove. The holes in thetop lining of the fire-chamber should each be provided with a damper, F,as shown in Figs. 1 and 3. The opening leading from the space Gr,between the top of the fire-chamber and the top plate of the stove,opens directly into the flue H, which leads to the chimney, whichopening is provided with a damper, I. J is a flue, leading down the rearside of the fire-chamber, formed between the bottom of the fire-chamberB and the top of the oven K, down between the front of the oven K and.the front plate of the stove A, back between the bottom of the oven andthe bottom of the stove, up along the rear of the oven, and out throughthe flue H. L is a draft-flue, which leads into the ash-chamber M belowthe grate C, so as to discharge the air to support combustion beneaththe middle part of said grate, and ,thus'make the combustion moreperfect.

One or more of the draft-tubes L may be used, and they may lead in fromthe door or from some other part or parts of the stove, as may bedesired or convenient. The draft-tube L, at its outer end, may beprovided with a damper, N, to enable the combustion to be controlled, asdesired.

0 is the hearth, which is made with a large opening through it, and isprovided, both upon its upon its upper and lower sides, with flanges orseats to receive the slide P upon its upper side, and the detachableash-box Q upon its lower side.

With this construction, when it is desired to cook without baking, orheating the lower part of the stove, the damper E is closed, the damperI is opened, and one or more of the dampers F, according as one or moreof the boiler-holes are to be used. This allows the heated products ofcombustion to enter the spaceG directly beneath the boiler hole or holesbeing used, and to pass out through the 'fiue H without heating thelower part of the stove. By closing the dampers F and I and opening thedamper E the heated products of combustion will pass, through the flueJ, entirely around the oven, and will escape through the flue H,enabling baking to be done without heating the upper part of the stove.By closing the damper E. and I and opening the dampers F the heatedproducts of combustion will pass into the space Gr, thence around theoven through the flue J and out through the flue H, heating the wholestove, enabling both cookingand baking to be don e, or the wholeradiating-surface of the stove to be used for warming the room. Byclosing the dampers F and opening the damper E and I, the heatedproducts of combustion will pass directly into the flue H, withoutwarming either the upper or lower part of the stme.

Having thus described my invention, Iclaim astnew and desire to secureby Letters Paten The arrangement of the dampers E F I in connection withthe opening in the rear end of the lined fire-chamber, the openings inthe top of said lined fire-chamber, the space between the top of thestove and the top of the fire-chamber, the flue J, and flue H,substantially as herein shown and described.
